Abstract (en)

A method for determining the mass of a soft product moving in a measurement device in which the product to be measured is moved through a vibrating system (1) capable of resonating at a natural frequency determined by the dimensions, masses and nature of the support of the vibrating system (1) when empty, in which this natural frequency is excited by means of an appropriate vibration source (2), in which the amplitude of the vibration is measured by means of a vibration detector (3), and in which the said amplitude measured in the vibrating system loaded with the product moving through it is compared with that measured in the vibrating system when empty in order to deduce therefrom the weight per unit length of the product moving therein. <IMAGE>
